MACC Jail and Court Support (MJAC) is an offshoot of MACC Legal and exists to ensure that when our comrades are arrested at demos in any borough, they are followed through the legal system until they come out safely, whether it be at the precinct, courthouse, or at One Police Plaza. MJAC participants work to make sure that when people come out of custody their immediate needs are met and that they are offered continued support through the resolution of their cases. MAJC is stuctured as a Signal-based phone tree, and is connected be MACC Legal when support is needed.

MJAC creates and provides "Freedom Care Packages" for those getting out of jail that contain food, cigs, literature and other necessities. MJAC has also a hosted a number of events where they gave out these Freedom Care Packages to non-MACC people getting out of jail to show solidarity and build support.
